Face Unlock
Settings > Security & Biometrics > Face unlock
Face recognition is an added security option that will let
you unlock the screen by simply raising your phone and
looking at the screen. Before you enter your face scan,
you will need to set a secure screen lock type and allow
Face Unlock to take pictures and record video in order to
complete the set-up process. Once you have completed
the set-up, your phone will also show notications on
your lock screen when you are looking at it.
Face scans can be deleted or updated as necessary. The
data used to recognize your face is kept private on your
phone.
Google Play Protect
Settings > Security & Biometrics > Google Play Protect
Google Play Protect runs a safety check on apps from
the Play Store before you download them. You can
congure Google Play Protect to regularly check installed
apps and your device for security risks and threats. App
updates are checked automatically, and you will receive
a notication if any security threats are detected and
removes known harmful apps from your device. Play
Protect is ON by default.
SIM Card Lock
Settings > Security & Biometrics > SIM card lock
Your SIM card includes information like your phone
number and voice/data plans, which can be compromised
if the SIM card is placed into another device. To help
protect it, you can create a SIM card PIN that will lock
access to the SIM.
